UPPER EAST SIDE, New York (WABC) -- Police have released video footage of a man wanted for another subway shoving incident.
On Monday night, the suspect pushed a man on the platform of the 6 train line at Lexington Avenue and East 77th Street on the Upper East Side.
The victim tumbled onto the tracks, but thankfully, good Samaritans helped him back up off the tracks before a train arrived.
Officials say the victim suffered scratches and bruises.
The suspect in the unprovoked shove got away. He was described as in his 30s, 5'7" tall, bald and with a medium build.
The incident on the Upper East Side was the third in nine days.
Meanwhile on Sunday around 5:30 a.m. on the 7 train platform at the 82nd Street - Jackson Heights train station, police say a man grabbed the purse of a 22-year-old woman and threw it to the ground.
When she confronted him, he punched her in the face and threw her down a flight of stairs.
The victim injured her left knee, right hand and suffered a compression fracture to her back. It was not a robbery and police say it was unprovoked.
Police say the suspect is in his mid 40s and about 5'10", 230 pounds.
Three days ago, a man was arrested for randomly pushing a woman toward the subway tracks in Brooklyn, causing the victim to bang her head against the stopped train.
Although that woman did not file a police report, law enforcement investigated the shoving and found that a subway recidivist was responsible.
The NYC Transit president greeted riders on Thursday and tried to assure them that safety is of top concern.
"It's everything that we're doing now, having more cops on the platform and on trains, having our conductors announce when they see cops getting on trains, or on platforms, you know, for a 10 car train," President Richard Davey said. "Sometimes our customers don't see that police are present or available. Reminding customers there are about a dozen stations with police stations in them so if there's an issue that they could address."
The governor and mayor announced a surge of police officers in the transit system over the weekend. And of course additional cameras are being installed as the MTA adds two cameras to every subway car over the coming months.
Anyone with information about Monday night's incident should contact police.
